These engines are unrelated to the F-series engines found in the mid 90s Honda Accord and Prelude. They share many properties with the H-series. These engines, unlike most F-series engines, have two overhead cams, a VTEC system for both the intake and exhaust camshaft, Fiber-Reinforced Metal cylinder liners , molybdenum disulfide-coated piston skirts for reduced friction, and uses a timing chain.

The F20C was designed with high maximum rpm capability in mind, for increased power output; redline is at 9000&nbsp;rpm, with VTEC engagement at 6000&nbsp;rpm. Its relatively long stroke of 84mm results in a mean piston speed of 4965&nbsp;ft/m, 56.42 mph or 25m/s, higher than any other production car to date. Power output is at 8300&nbsp;rpm in North America and Europe. The Japanese version, which has a higher compression ratio, is capable of at 8600&nbsp;rpm.
